COMPUTATION OF TURBULENT FLOWS AROUND ROTATING BODIES USING UNSTRUCTURED GRIDS PARTL.Oktay GONC, Mehmet Ali AK, M.Haluk AKSEL and Ismail H. TUNCER This paper, first in a series of two, presents the development of a 3-D parallel flow solver for turbulent flows around rotating bodies using unstructured grids. Cell centered finite volume solver which employs Roe�s upwind flux differencing scheme, Spalart-Allmaras turbulence model and Runge-Kutta explicit multistage time stepping scheme is presented. Arbitrary Lagrangian Eulerian formulation is implemented for moving grids. The computational grid is partitioned by METIS and PVM is used for inter-process communication. The main objective of this study is to be able to solve unsteady turbulent flows around rotating missile configurations and to evaluate the aerodynamic stability derivative coefficients. |
